OAR-LOCK.

SPECIFICATION forming part of Letters Patent No. 591,509, dated October 12, 1897. Application led February 27, 1897. Serial No. 625,361. (No modelJ To all whom, t may concern,.- Y

Be it known that I, JOHN R. SUPPLE, a citiin the county of San Diego, State of California,

have invented certain new and useful Improvements in Oar-Locks, of which the following is a specification, reference being hadl therein to the accompanying drawings.

This invention relates to that class of oarlocks which have an oar-sleeve provided with trunnions received in the upper ends of a horizOntally-swiveled yoke to allow all necessary play to the oar; and the objects of my invention are to produce a simple and efficient oar-lock of this class of two cast pieces of metal having interlocking journals and bearings ready for use as soon as cast, and to dispense with the customary necessity of iitting these parts, and said bearin gs, being of knifeedge form, give to said parts the necessary play with a minimum of friction, as will-he hereinafter set forth, and pointed out in the claims.

In the accompanying drawings, Figure l is a perspective View of an oar-lock constructed in accordance with my invention. Fig. 2 represents, in front View, the horizontally-swiveled yoke, carrying on its upper endsthein- .ner (oar-supporting) sleeve, the latter being show n in vertical section with one of its hoodbearings locked to one of the branches of the yoke, while the other bearing has its bottoml A2 terminate, preferably, in acute or substantially knife-edge journals a2 to reduce their friction to a minimum in their bearings. The ends of said branches A2 are also provided with lugs a3 to engage with iianges projecting inwardly from hood-bearings projecting laterally from the sides of the oar-Supporting side ofthe lugs B3.

Vform of a ring open at the top or having two branches B2, between which an oar can be introduced.

Projecting from the outer edge of each branch B2, about half-way of its length, there is a large hollow lu g B2, provided with a chamber adapted to receive the upper ends or knife-edge journals a2 on the upper ends of the branches A2, and also their lugs as, the latter being to engage with the flanges b2, projecting from the inner edge of the hood pendent from the bearings h2 in the under The walls of the .chamhers formed under the hollow lugs protect the journals and bearings on the under side of said lugs against the splashing of water thereon.

After obtaining the two castings constituting the oar-lock, of bronze or malleable metal, the chambered lugs B3 are placed on top of the hearings on the upper ends of the branches of the yoke, and with one or two blows of a hammer against the outer face of the lugs B3 or by pressure with a press against both lugs the oar-lock is completed, ready for use, and the parts remain permanently connected together.

Having I claiml. An oar-lock consisting of a yoke having the upper ends of its branches provided with lugs a3 projecting from their outer sides, in combination with a sleeve having chambered lugs projecting from its outer sides, each lug provided with a iiange b2 inwardly projecting from its lower end,substantially as described.

2. In an oar-lock the combinationof a yoke having its upper ends substantially knifeedged and provided with lugs a2 projecting from their out-er sides, with a sleeve having now fully described my invention,

chambered lugs constituting acute bearings,

each lug provided with an inwardly-projecting flange on its lower end substantially as described.

In testimony whereof I affix Iny signature in presence of two witnesses. Y
